Arsenic aids tumor imaging when joined to cancer-homing drug, UT Southwestern researchers find
Arsenic linked to a drug that binds to the blood vessels of cancerous tumors provides a powerful imaging agent that could one day allow physicians to detect hard-to-find tumors and more closely monitor cancer's response to therapy, researchers at UT Southwestern Medical Center have found. view more (2008-03-03)
Monkeys' calls - the beginnings of human language?
Rhesus macaques communicate between themselves using a complex series of sounds that can signify things as distinct as the presence of danger, particular social relationships, emotions or food alerts. Now scientists in the latest issue of Proceedings of the National Academy of Sciences of the United States of America, while analyzing the brain... view more... (2004-12-17)
Physicists offer new approach to studying antimatter
What happens when two atoms, each made up of an electron and its antimatter counterpart, called the positron, collide with each other? view more (2005-11-01)
Drug helps cognitive function in brain tumor patients after radiation
A drug that is marketed to treat Alzheimer's disease also improves cognitive function, mood and quality of life in brain tumor patients following radiation therapy. view more (2006-03-20)
The closest look ever at native human tissue
Seeing proteins in their natural environment and interactions inside cells has been a long-standing goal. Using an advanced microscopy technique called cryo-electron tomography, researchers from the European Molecular Biology Laboratory [EMBL] have visualised proteins responsible for cell-cell contacts for the first time. view more (2007-12-06)
New molecular imaging techniques may lead to advances in disease treatment
A promising new technique has been developed that will enable more accurate non-invasive positron emission tomography (PET) imaging of new cells injected into the body, according to researchers at SNM's 55th Annual Meeting. view more (2008-06-17)
PET imaging identifies aggressive kidney cancers that require surgery
The ability to identify an individual's specific tumor type prior to surgery could have important implications for the management of patients diagnosed with kidney cancer. view more (2007-03-07)
New imaging compound might 'see' Alzheimer's earlier
A new imaging molecule that can detect and map plaques and tangles in the brains of people with Alzheimer's disease could eventually lead to earlier diagnosis of the devastating disease, researchers at the University of California, Los Angeles report in the Dec. 21, 2006, issue of the New England Journal of Medicine. view more (2006-12-21)
First semiconductor-based PET scanner demonstrates potential to aid in early diagnosis of disease
Evaluations of the first-ever prototype positron emission tomography (PET) brain scanner that uses semiconductor detectors indicate that the scanner could advance the quality and spatial resolution of PET imaging, according to researchers at SNM's 55th Annual Meeting. view more (2008-06-17)
Imaging technique is highly accurate in diagnosing, locating pancreas defects in newborns
The noninvasive imaging technology called positron-emission tomography (PET scan) is extremely accurate in diagnosing a type of congenital hyperinsulinism (HI), a rare but severe imbalance of insulin levels in newborns. view more (2007-01-30)
Study explains why up to eight percent of cancers go undetected
A few years ago, Medhat Osman, M.D., Ph.D., had a patient who was scanned due to a suspicion of lung cancer using positron emission tomography (PET) and computer tomography (CT) technology. The scan came back negative, but the patient then complained of a problem with his leg. view more (2005-06-15)
PET Outperforms CT In Characterization of Benign and Malignant Lung Nodules
Researchers involved in a large, multi-institutional study comparing the accuracy of positron emission tomography (PET) and computed tomography (CT) in the characterization of lung nodules found that PET was far more reliable in detecting whether or not a nodule was malignant. view more (2008-02-07)
Diabetes Slows Nerve Recovery After Heart Transplant
Diabetes has a detrimental effect on a person's ability to recover from a heart transplant, notes a study in the September Journal of Nuclear Medicine. view more (2006-09-06)
Scans spot hidden tumors in rare cancer syndrome
Researchers at Dana-Farber Cancer Institute report that full-body PET/CT scanning detected unsuspected, treatable tumors in 3 of 15 patients with Li-Fraumeni syndrome (LFS), a rare genetic cancer syndrome for which no screening tests have been recommended. view more (2008-03-19)
Study shows PET can measure effectiveness of novel breast cancer treatment
A new study published in the July issue of The Journal of Nuclear Medicine shows that positron emission tomography (PET) scans in mice can be used to determine whether a novel type of breast cancer treatment is working as intended. view more (2009-07-02)
Survey reveals British public don't know the difference between quarks and DNA - do you?
A survey commissioned by the Institute of Physics (IoP) has found that a staggering 98 percent of UK adults don't know what the world around us is made of. Just under two percent of those asked gave the right answer, quarks, the basic building blocks of all matter in the universe. The survey asked over 500 people what makes up the nucleus of an... view more... (2004-03-30)
PET accurately identifies esophageal cancer patients' positive responses to chemotherapy
Early metabolic imaging with positron emission tomography (PET) accurately identifies patients responding to chemotherapy for esophageal cancer, noted German researchers at the 54th Annual Meeting of SNM, the world's largest society for molecular imaging and nuclear medicine professionals. view more (2007-06-04)
Scientists use PET scans to monitor lung inflammation noninvasively
A noninvasive approach for assessing lung inflammation should accelerate efforts to develop drugs for inflammatory lung conditions like cystic fibrosis and pneumonia, scientists at Washington University School of Medicine in St. Louis report. view more (2006-03-09)
Increased role for PET imaging could improve cancer care
A limitation of current cancer care is the difficulty of quickly assessing how well a therapy is working. However, expanding the use of existing positron emission tomography (PET) technology can provide early and accurate assessment of a tumor's response to a particular therapy allowing physicians to better tailor a patient's treatment. view more (2006-02-02)
Cocaine's effects on brain metabolism may contribute to abuse
Many studies on cocaine addiction - and attempts to block its addictiveness - have focused on dopamine transporters, proteins that reabsorb the brain's "reward" chemical once its signal is sent. view more (2008-02-19)
